The volume of the solid obtained by rotating the region enclosed by y= =', y = 5x, about the line y = 25 can be computed using the method of discs or washers via an integral V = v ? dx with limits of integration a = and b = dyConsider the region enclosed by x + 4y = 26 and x + 6 = y'. Using integrals, the area of this region can be computed two different ways. (a) Integrating with respect to r: [ f(x)de + ( 9(x) do where a = , b = C= and f(x) = 9(I) = (b) Integrating with respect to y: [h(y) dy where of = B = and h(y) = (c) Determine the area of the region
